Abstract

A brushless motor start method includes: an initial position moving step (ta to tc) for rotating/moving a rotor to a predetermined initial position by DC excitation; forcible commutation step (tc to td) for performing electrical connection according to a predetermined electrical connection pattern so as to rotate the rotor from the initial position; and a shift step (td) for shifting to the rotation control based on the estimated rotor rotation position. The initial position moving step includes a first step (ta to tb) for increasing the DC excitation current up to a first current value so that the rotor is rotated/moved to a preparatory excitation position apart from the initial position and a second step (tb to tc) for increasing the DC excitation current up to a second current value which is higher than the first current value so that the rotor is rotated/moved from the preparatory excitation position to the initial position.
